Protestants claim the Catholic Church uses Circular Reasoning - Is that True?

[00:00:00]The first false teaching of the Roman Catholic Church is the teaching that they are the one true church. The problem with the claim to the one true church is that it's circular reasoning.

[00:00:10]We are the one true church because we say we're the one true church. And uh because we are the one true church, we can say we're the one true church and therefore we're the one true church.

[00:00:20]It's not uncommon to hear Protestants insist that the Catholic Church's claim to be the one true church is based on circular reasoning or that it can't be verified.

[00:00:30]Others claim that the church's teaching on the power of the magisterium of the Catholic Church to issue infallible definitions is nothing but circular reasoning. Is that true? Is the church's teaching in these areas based on circular reasoning?

[00:00:46]No, they're not. As we shall see, the Catholic argument goes like this.

[00:00:53]Premise one, Jesus Christ founded, instituted the Catholic Church as a visible hierarchical community with teaching authority and appointed leaders, the apostles and their successors to continue his mission to ensure the faith is guarded and handed on in its entirety and without corruption.

[00:01:13]Premise two, Jesus Christ, God in the flesh, promised and granted the magisterium, the teaching office of the church, the charism, supernatural gift of infallibility in definitively defining doctrines on faith and morals, meaning protection from error in those specific acts through the Holy Spirit's assistance.

[00:01:37]conclusion. Therefore, the Catholic magisterium possesses infallibility from God when it exercises this authority under the proper conditions.

[00:01:48]This argument avoids circular reasoning by grounding the claim in an independent source, namely the historical actions and promises of Jesus Christ, who is presented as the divine founder of the Catholic Church external to the magisterium itself.

[00:02:06]The magisterium's authority derives from Christ, not from a self-declaration.

[00:02:14]This argument is not circular because the premises stand or fall on historical, scriptural, and theological evidence about who Jesus was and his deeds and words, not on assuming the magisterium is already infallible by a self declaration.
